Cagayan de Oro City (CNN Philippines) — Prolonged heavy rain due to two weather disturbances caused flash floods in various parts of Cagayan de Oro City and Misamis Oriental on Monday.

Vergel Lago, City Disaster Risk Reduction and Management Office (CDRRMO) weather monitoring chief, said a low pressure area and the tail end of the cold front caused downpour that started at 2 p.m. Monday.

Although the rain stopped at 2 a.m. Tuesday, Cagayan de Oro City disaster officials declared a state of calamity following massive flooding in the city.

Authorities carried out forced evacuation, especially those living near the Ipunan River.

According to Allan Porcadilla, the City's Disaster Administrator, more than 1,200 families or close to 5,000 individuals have been evacuated, with 221 families from near the Ipunan River.

Porcadilla also said they are closely monitoring this river system as it has reached the critical level.

Meanwhile, no casualties and injuries have been reported.

Landslides, closed roads

Lago said the CDRRMO hotline has been getting calls from residents asking for rescue after creeks overflowed, with floods reaching waist-high.

In addition, a landslide was reported below the Pryce Plaza Hotel in Mastersons Avenue, Carmen and in Paglaum, Camaman-an.

Radio reports also said there were houses nearly washed out in Barangays Gusa and Agusan, while a tree fell and blocked the road in Macanhan, Carmen, causing heavy traffic in the area.

As of 6 p.m. Monday, flooded and impassable areas include:

Limketkai area

C.M. Recto

Villarin Street

JV Serina Street

Gumamela Extension

Gaabucayan to Osmeña

Camaman-an Elementary School

Pryce Plaza

Zone 7 Patag

Barangay Agusan

Zayas Muco

Balongis to Balulang

Osmeña Cogon

Kauswagan Highway

Zayas, Carmen

Gaabucayan Street

Osmena Street

Camaman-an

Balulang

Rescue teams and equipment — together with the police, military, the Philippine Coast Guard and the Philippine Red Cross — have been deployed to the affected areas.

Power shutdown

In addition, the Cagayan Electric Power and Light Company Inc. (Cepalco) had shut down electricity lines in highly flooded areas, such as Carmen, Camaman-an, Macanhan and C.M. Recto.

Cepalco spokesperson Marilyn Chavez said power in these areas would be restored immediately once it was safe to do so.

"We are prioritizing the safety of highly flooded areas because live wires may be dangerous during floods," Chavez said. "We are asking for the cooperation of the public to report any observations of loose wiring in their areas so that Cepalco can handle it immediately."

Flood in rest of Misamis Oriental

In Misamis Oriental, intermittent rain also led to floods in Gingoog City after the Gahub River spillway in San Miguel Village overflowed.

As of 4:30 p.m. Monday, the approach to a bridge in Kalanawan, Sungay in Alubijid town was damaged — making the area impassable except to motorcycles.

Flash floods were also reported near the Tingalan, Nangcaon and Awang River in Opol.
